To all 't0/10m 'it may concern Be it known that I, 'CHARLES F. TOWN- sAN, a citizen of the United States, at Mitchell, in the county of State of South Dakota, have tain new. and useful Improvements in Valvedjusters, of which the-.following is aspeeiication. A

This invention relates to devices for adjusting the lift of puppet valves used on in ternal combustion engines; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is and Fig. 2 isa side View, of a spring band usedin carrying out this invention. Fig. 3 .is a plan view, and Fig. 4 is an. end view, of an adjusting disk. Fig. 5 is a side view of portions of a push rod, and a `valve stem and (fo-acting parts, provi ledwith an adjuster according to this invention.

The push rod C, used to raise theV Valve,

is slidable vertically in a stationaryguide Il, and the valve stem A 1s arranged in line vwith the push rot. The valve has a spring 'D wl'iich'bears on a collar (Z secured on the valve stem, and which normally holdsI the valve to its-seat in the usual why. The valve stem is a little lsmaller in diameter than the push rod.

A cylindrical spring band l" is provided, and is forced partway over the uppereml portion oi the upon the push toi-ms an open-topped chamber having a vertical slot in one side.

Patented Jan. 27,1914. Aserial No. @Sasse ,is formed between the edges of the spring band which are separated as shown, when it is forced onto the push rol. In the chamber thus formed are placed spacing or adjusting disks E. stem A is arranged above the adjusting disks, in the upper part of the chamber, and is freely slidable in the chamber. I

`The lift of the valve is varied by inserting more or temer disks in the chamber, and the disks can be. removed and inserted at the open top of the chamber without removing the spring band from the push rod, when the valve and its stem are lifted out. The disks are removed y inserting any suitable instrument in the longitiulmal opening,r or slot between the edges of the spring band.

lVhat I claim is: i

The combination, with a slidahle push rod, and a valve stem of smaller diameter than the push rod; of a sjning band encircling the end portion ot the push rod and held in el'igagement therewith by its gwn and forming an open-topped chan'iber, for the valve stem, having a slot in one side; and an adjusting disk interposed betwcen the push rod and the valve stem, said disk being removable from the chamber without band trom the push rod.

In testimony whereof l have signed my mme to this specification in the presence of l' ung witnesses. 4
